in form there many fields data loaded server, there dependent data lists , while performs data loading want freeze interface - example, showing progress bar. layer large z-index , on others , progress-bar in corner. example.. i know how using gwt or vaadin : modal window progressbar long tasks how using angularjs? basically, know how using javascript. the problem quite common.. maybe there ready solutions? i grateful information. all. the easiest option integrate solution promise tracker if need block out screen while application bootstraps ngcloak allows display message while angular initializing.

i trying submit code 'small factorials' problem on spoj. runs on ide shows run time error (nzec) on spoj. please suggest solutions. import java.util.scanner; class factoria { public static void main (string[] args) throws java.lang.exception { int t, n; int multi = 1; scanner tc = new scanner(system.in); t = tc.nextint(); for(int i=0;i<t;i++){ scanner nc = new scanner(system.in); n = nc.nextint(); for(int f=1;f<=n;f++){ multi = multi * f; } system.out.println(multi); multi = 1; } } } your runtime error because try initiate new scanner on system.in when have 1 open. seems fail on java 8 although seems run ok on java 7 - both tested on ideone . there no need initiate new scanner . if remove line scanner nc = new scanner(system.in); and use tc.nextint(); instead of nc.nextint(); should work. i note you

so reading code website: http://www.geeksforgeeks.org/write-a-c-program-to-find-the-parity-of-an-unsigned-integer/ and shows how determine whether number has or odd parity. however, don't understand why runtime efficiency log(n). here code reference: # include <stdio.h> # define bool int /* function parity of number n. returns 1 if n has odd parity, , returns 0 if n has parity */ bool getparity(unsigned int n) { bool parity = 0; while (n) { parity = !parity; n = n & (n - 1); } return parity; } the runtime efficiency o(log(n)), n value of integer pass in. however, that's unconventional way use o notation. more frequently, o notation expressed in terms of size of input in bits (the # of bits needed represent input), in case size of input k=o(log2(n)) , runtime o(k). (even more accurately, runtime Θ(s) s number of bits set in n, although assumes bit operations o(1)).

i need list unique values of attribute in group, when attribute has specific value. making work in xsl 1.0 tricky understand. thanks post, have groupings defined allow me perform counts when attributes match specific criteria. i'm stumped on being able list unique values 1 specific attribute, attribute equal specific value, within members of current group. as always, make more sense example source data , code. here sample xml <?xml version="1.0" encoding="utf-8" standalone="yes"?> <group1> <group2> <locationidentification locationid="0610390" /> <locationidentification1 locationqualifier="12" locationid="uslgb"/> </group2> <group2> <locationidentification locationid="0610612" /> <locationidentification1 locationqualifier="12" locationid="uslax"/> </group2> <group2> <locationidentifica

why work: function test_func(a, b) + b end test_func((1, 2)...) but not? macro test_func(a, b) + b end @test_func((1, 2)...) is bug in julia? macros operate on surface syntax , @test_func isn't seeing result of splat. instead, sees splat operation itself! always, great way inspect quote , see syntax macro operating on: julia> :(@test_func((1,2)...)) :(@test_func (1,2)...) julia> meta.show_sexpr(ans) (:macrocall, symbol("@test_func"), (:..., (:tuple, 1, 2))) so macro receiving 1 argument (not two), , it's expr(:..., expr(:tuple, 1, 2)) . notice tuple (1,2) is getting passed macro, it's hidden away inside splat operation. dig expr , kind-of-sort-of implement splatting yourself: julia> macro test_func(as...) if length(as) == 1 && isa(as[1], expr) && as[1].head == :... && isa(as[1].args[1], expr) && as[1].args[1].head == :tuple a, b = as[1].arg

from can tell, fabric.js can load either jpg or png files. fails when try load tiff file. idea? fabric.image.fromurl('my_image.tif', function(oimg) { canvas.add(oimg); }); this not problem fabricjs, more browsers in general not support tiff file format . ie , safari being exceptions less mainstream browsers. workarounds however, possible read , parse tiff files manually. read tiff can use example tiff-js . may able plugins browser can decode tiffs (the latter possibly require end-user install plugin well). though, recommend convert tiff example png general use. similarly, not able save out tiff either same reasons above, feel free @ canvas-to-tiff solution (free).

this function not making sense me. ive added print statements on place figure out whats going on , still dont it. i'd grateful if explain me. def f(s): if len(s) <= 1: return s return f(f(s[1:])) + s[0] print(f("mat")) this see happening. start string of length 3 , bypass if statement. work on inside f(s[1:]) first. have string of length 2 ("at") again bypasses if statement , enters f(s[1]) gives string of length 1 ("t") enters if statement , returns "t". trail goes cold me. from print statements, see new string of length 2 created , subsequent "a" gets returned. final product ends being "atm". "m" being tagged on end "+ s[0]" part why "atm" , not "tam"? i've spent few hours on , cant make rain. appreciated. expand whole thing out long steps filling in function calls doing. deal brackets deepest/most embedded first. deal function

so on net i've come across several ways preload / redirect webpage. now's question proper way handle redirect preload (load next page async while still showing current page) $.get("page.php", function (data) { document.open(); document.write(data); document.close(); window.history.pushstate("title", "title", "/page.php"); $.cache = {}; }, "html"); or should better stay regular redirect? window.location = "page.php"; the next page contains fullscreen video , soundtrack (audio) thanks. you can use ajax load next page asynchronous. here example of simple ajax request using get method, written in javascript . ajax stands asynchronous javascript , xml, , xmlhttprequest object behave ajax, async parameter of open() method has set true: xhr.open('get', 'send-ajax-data.php', true); get-ajax-data.js: // client-side script. // initialize ajax request. var

i have button in first layout , want when user clicks on it, shows activity , never shows first activity. i tried : boolean isfirstrun = getsharedpreferences("preference", mode_private) .getboolean("isfirstrun", true); if (isfirstrun) { //show start activity startactivity(new intent(mainactivity.this, firstlaunch.class)); toast.maketext(mainactivity.this, "first run", toast.length_long) .show(); } getsharedpreferences("preference", mode_private).edit() .putboolean("isfirstrun", false).commit(); i doubt, because may won't hit getsharedpreferences() line, , navigated new activity firstlaunch . so think should like, if (isfirstrun) { //show start activity getsharedpreferences("preference", mode_private).edit() .putboolean("isfirstrun", false).commit(); startactivity(new intent(mainactivity.this, firstlaunch.class)); toast

i've looked around couldn't find single tutorial on getting started phantom. although being actively developed dedicated folks, find surprising there no quickstart tutorials around. please share links tutorials if 1 has come across you can checkout phantom-dsl examples in source folder, if not, i've uploaded example github showing how modeling cassandra tables in scala using phantom-dsl according documentation. https://github.com/thiagoandrade6/cassandra-phantom

suppose have fragment shader starting #version 120 , vertex shader #version 150 compatibility . combination appears work afaict, go against opengl or glsl specifications? couldn't find information discusses issue. if there's none indeed, should take "not forbidden" or "not approved"? no, there no requirement shader versions match. there requirement profiles match, relates mixing desktop , embedded glsl. discussed briefly in glsl specification, implications of mixing different shader versions of compatible profiles not discussed. opengl shading language 4.50  -  3.3 preprocessor  -  p. 14 shaders core or compatibility profiles declare different versions can linked together. however, es profile shaders cannot linked non-es profile shaders or es profile shaders of different version, or link-time error result. when linking shaders of versions allowed these rules, remaining link-time errors given per linking rules in glsl version correspond
